Dyson spheres: Alien power plants may be drawing energy from 7 stars in the Milky Way [Video]

Scientists claim to have detected signs of a long-hypothesised alien power-generation technology in the Milky Way galaxy, hidden away in a trove of astronomical data.

These hypothetical “Dyson spheres” are mega structures that only extremely technologically advanced civilisations would be able to build, designed to draw energy from stars.

Researchers say they have developed a new way to look for signs of alien power generation in a project called Hephaistos, named after the Greek god of fire and metallurgy.

To start with, they analysed data collected by astronomical surveys Gaia DR3, 2MASS and WISE to flag Dyson sphere candidates in the Milky Way.

“In this study, we present a comprehensive search for partial Dyson spheres by analyzing optical and infrared observations from Gaia, 2MASS, and WISE,” the researchers write in a study published in the journal Monthly Notices of the Royal Astronomical Society.

“A specialised pipeline has …
